// ============================================================================// CLASS:        txCString// DESCRIPTION:  A Text String class designed for basic UNICODE text strings, //               and compatibility with ASCII character sets.// REQUIREMENTS: This class requires a previously defined typedef of type//               ''txchar'' which defines which type of character set to use.                 txILanguage, <iostream>// AUTHOR:       Ron Penton// DATE:         02-01-2001// ============================================================================// Revisions:// ----------------------------------------------------------------------------// 1.0          02-01-2001      22:40// Initial Version// ----------------------------------------------------------------------------// 1.1          03-06-2001      10:57// - Added UnicodeType enumeration.// - Removed character representation. All character handling will be done//   with internal structures now.// - Added reliance upon DKSILanguage class interface.// ----------------------------------------------------------------------------// 1.2          03-06-2001      15:51// - changed back to compile time character representation.// - removed UnicodeType enumeration.// ----------------------------------------------------------------------------// 1.3          03-06-2001      22:00// - changed class name to txCString to reflect new naming convention.// ----------------------------------------------------------------------------// 1.4          03-06-2001      22:49// - added preprocessor directives for figuring out txchar type.// ----------------------------------------------------------------------------// 1.5          03-07-2001      13:57// - removed preprocessor directives and placed them in separate file// - added titlecase() method// - added concatenate() method// - added assign() method// ----------------------------------------------------------------------------// 1.6          03-07-2001      16:32// - changed interface a little, all strings operate with one txILanguage at//   a time// - added setLanguage() method.// - added getLanguage() method.// - added newString() and deleteString() helper methods.// - added copyString() helper method.// ----------------------------------------------------------------------------// 1.7          03-08-2001      18:04// - removed + operator, due to reference and lost pointer problems.// - added second newString() method, which takes a pre made string.// ----------------------------------------------------------------------------// 1.8          03-11-2001      12:53// - added iostream extraction and insertion operators, only work with regular//   ASCII strings, extended UNICODE characters are truncated to 8 bits for//   ostream insertion. These operators are for basic demonstration use.// - re-added + operator, now that i know how to make it work.// ----------------------------------------------------------------------------  

  // ----------------------------------------------------------------------------//  Name:           txCString::resize()//  Description:    Resizes string to a new length.//                  If new length is lower, letters are cut off end.//                  If length is higher, extra letters are filled//                  with p_fill.//  Arguments:      - p_size: new size of the text//                  - p_fill: character to fill extra spaces with.//  Return Value:   None.// ----------------------------------------------------------------------------    void resize( int p_size, txchar p_fill );  

  // ----------------------------------------------------------------------------//  Name:           txCString::m_refCount//  Description:    pointer to an integer which contains the current reference//                  count for the string. This should be incremented whenever//                  a new string is allocated which uses this string''s contents//                  decremented when a string is changed or deleted, and//                  the reference count should be deleted when no more//                  references exist to this string. (*m_refCount == 0).// ----------------------------------------------------------------------------    int* m_refCount;
